Go to the bathroom early, put your phone down and get your snacks ready the night before, because, if the first episode of "Blindspot" is any indication, the second season isn't going to provide any dull moments.

Fans of "Person of Interest" have waited almost a full year to see what follows the season finale - and what will become of the watchdogs, who, for four seasons, have used a set of computer-generated numbers to watch over the just and unjust (protecting the innocent and punishing the guilty).

From her blind audition, when three chairs turned, Hannah Huston has earned rave reviews for her performances (including covers of Allen Stone's "Unaware" and Sia's "Elastic Heart"), while also charting on iTunes.

At the conclusion of Monday's episode of "The Voice," coach Adam Levine said Alisan Porter is "the Jordan Smith of this season." He likened the former actor and "Curly Sue" star to the season nine champion, whose high notes made him the frontrunner from his blind audition through the finale.

On the back end of "Grimm's" fourth season last year, Juliette (Bitsie Tulloch) turned into a Hexenbiest - nasty and super-powerful - betrayed Nick's mother and then tried to kill Nick - before taking a double-dose of crossbow courtesy of Trubel.

Once again, it's up to a stylish Brit to save the world. This time, however, it isn't Daniel Craig's James Bond fighting off Spectre, but rather David Harewood's J'onn J'onzz shielding the populace from White Martians.

Actress Jacqueline Toboni said fans are about to learn why her character, our favorite female Grimm, was taken; why she was kidnapped and then half-dead when she found Nick last episode; and what's up with her fancier clothes and souped-up ride.

Season after season, singers on NBC's "The Voice" claim there is nothing harder than the "Battle Rounds." The competition's second stage pits two artists in a duet-duel, wherein each must find harmony while showcasing superiority to advance to the third stage, the "Knockouts."

Every year, thousands of singers tryout for NBC's "The Voice." Their ultimate goal, of course, is to land a recording contract, make an album and tour. But their immediate goal is to convince just one coach to take a chance and turn a chair.

On "Heroes Reborn," Judi Shekoni's character, Joanne, has horrifically lost her son - she believes to "evos," or evolved humans - and she's not in a good place. When the series begins, the former housewife is on a particular quest.

"Dancing with the Stars" was designed to shine a spotlight on celebrities - for better or worse - trying their hand at ballroom dancing. But pro Sharna Burgess said the hit ABC series has done much more than that since debuting a decade ago.

While M. Night Shyamalan's stories are varied - from a boy who sees dead people ("The Sixth Sense") to a faux superhero ("Unbreakable"), a mysterious, sheltered community ("The Village") to a far-off sci-fi future filled with "Abbies" ("Wayward Pines") - there is one big constant: At some point, each tale will have a shocking twist.

Though "Grimm" could technically be classified as a procedural (albeit one with big mythological weapons and even bigger, monstrous bad guys), Reggie Lee said the show has one big advantage over "bad guy of the week" crime-fighting series.

Syfy's "12 Monkeys" bounces back and forth between decades with reckless abandonment - rewriting the storyline over and over again in the process. Such plot twists make it impossible to predict what will happen next, thereby making the show hard to miss.
